Abstract
A method, apparatus and system for synchronizing contents are provided. The method for synchronizing contents includes comparing contents stored in a first device with a content list stored in a second device, and deleting contents from the content list or adding contents to the content list. Therefore, is possible to prevent incorrect contents from being browsed even when contents are not completely synchronized.
Claims30
A method for synchronizing contents, comprising:
- comparing contents stored in a first device with a content list stored in a second device, and determining at least one first content which is in the content list but not stored in the first device;
- deleting the first content from the content list;
- comparing contents stored in the first device with the content list from which the first content has been deleted, and determining at least one second content which is stored in the first device but not in the content list from which the first content has been deleted;
- and
- adding the at least one second content to the content list from which the first content has been deleted,
- wherein the deleting step is performed before the adding step.

A method for synchronizing contents, comprising:
- deleting contents in a first group from a content list stored in a second device based on contents stored in a first device;
- comparing contents stored in a first device with the content list from which the first content has been deleted, and determining a second group which is stored in the first device but not in the content list from which the first content has been deleted;
- and
- adding contents in the second group to the content list from which the first content has been deleted,
- wherein the deleting step is performed before the adding step.
2 more elements
A content playback apparatus which performs content synchronization with an external device, the content playback apparatus comprising:
- a storage unit which stores a content list;
- and
- a synchronization controller which compares the content list with contents stored in the external device, determines at least one first content which is in the content list but not stored in the external device, deletes the at least one first content from the content list, compares the content list from which the first content has been deleted with the contents stored in the external device, determines at least one second content which is stored in the first device but not in the content list from which the first content has been deleted, and adds the at least one second content to the content list from which the first content has been deleted,
- wherein the synchronization controller performs the deleting before the adding.
1 more element
A system for synchronizing contents stored in a first device with contents stored in a second device, the system comprising:
- the first device which transmits a content, which is not in a content list stored in the second device, among the stored contents to the second device, if the first device is connected to the second device;
- and
- the second device which compares the stored content list with the contents stored in the first device, determines at least one first content which is in the content list but not stored in the first device, deletes the at least one first content from the content list, compares contents stored in the first device with the content list from which the first content has been deleted, determines at least one second content which is stored in the first device but not in the content list from which the first content has been deleted, and adds the at least one second content to the content list from which the first content has been deleted,
- wherein the second device performs the deleting before the adding.
1 more element
A method for having same contents in a first device and a second device, the method comprising:
- establishing a communication between a first device including a content list, to a second device storing second device contents;
- and
- automatically synchronizing the second device contents with the content list of the first device when the communication is established, the synchronizing comprising:
- comparing the second device contents with the content list, and determining a first content which is in the content list but not stored in the second device;
- deleting an identifier of the first content from the content list;
- comparing the second device contents with the content list from which the first content has been deleted, and determining at least one second content which is stored in the second device but not in the content list from which the first content has been deleted;
- and
- adding the determined at least one second content to the first device,
- wherein the deleting is performed before the adding.
6 more elements
A method of synchronizing contents between a first device and a second device, the method comprising:
- deleting identifiers of first contents from a content list of the first device, not being stored in the second device;
- determining second contents stored in the second device, that are not in the content list of the first device;
- and
- adding the second contents to the first device,
- wherein the deleting and the determining are alternatingly performed and after the alternatingly performing of the deleting and the determining is completed, the adding is performed,
- wherein the deleting is performed before the adding.
